Milestone:  To Be Determined               |  Component:  container
  Version:  Boost 1.54.0                   |   Severity:  Optimization

-------------------------------------------+--------------------------
 As discussed on boost-users mailing list (see "[container.string] why
 isn't memcpy used in the internals?"), the performance of constructing
 boost::container::string from C string is a lot worse than in case of
 std::string. That's because boost::container::string does not use
 std::char_traits::copy for input C string copying but rather copies it
 character by character.

 Environment:
 - Ubuntu 12.04 (i386)
 - gcc 4.6.4
 - Boost 1.54.0
